Ive read not to add any food until the crop is empty. I believe i made that mistake with my little chick. Her crop was almost empty, and i gave her egg yolk. Next time i massaged her crop she vomited the egg yolk. Her crop never emptied and i believe she then developed pendulum crop. She didnt make it. I feel like the egg yolk and little bit of crumble I added for nutrition just made things worse.Update: She's pooping a lot, and her crop is a lot easier to massage. The sediment is a lot more loose. It's still oversized, but I thiiiiiink it's getting better!
